Abstract: 1363726 Dispersing gases in liquids; contacting liquids and gas L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE and COMPAGNIE FRANCAISE D'ETUDES ET DE CONSTRUCTION TECHNIP 8 July 1971 [9 July 1970] 32230/71 Headings B1C and B1R In a method and apparatus for making a homogenous dispersion of a two-phase (gas/ liquid) fluid, a heterogeneous mixture enters at 13, Fig. 1, and passes into a separation zone 61 where it separates into a liquid phase 21 and gaseous phase 22 below a distribution plate 19 consisting of concentric interfitting rings 26, Fig. 4, the gas/liquid separation surface benig located in the region of perforations 23 in riser tubes 20. Some of the gas passes up the riser tubes carrying with it some liquid and is ejected horizontally through holes 25 at the top of the riser tubes, part of the liquid forming a layer on the plate 19. The remainder of the gas passes up through perforations 32, 33 in the plate 19 and through interstices between the rings and tubes and entrains liquid from the layer on the plate 19. The distributed fluid streams combine to form an upward fluid flow which is further homogenized by passage through a labyrinth formed by the spaces between heat exchange tubes arranged in two coiled bundles each represented by a single tube 7, 10. In a modification, Fig. 7 (not shown), the plate 19 is fluid-tight and the riser tubes have open tops. The liquid layer being entrained by gas issuing from the tubes. Other forms of riser tube are described with reference to Figs. 5a-d and 6, not shown. Another embodiment (Figs. 10-12, not shown) is arranged for downward passage of the fluids, the heterogeneous mixture entering the top of the apparatus and the liquid forming layers on two plates (65, 66) formed by the upper and lower flanges (48, 49) of concentric interfitting rings (47) and being uniformly distributed by perferations (50), therein; while the gas is uniformly distributed by passage through downcomer tubes (41). In the event of the liquid level rising, overflow may take place through slots (45) into the downcomers. Additional tubes (42) are provided to equalize the pressure between the plates with that in the separation zone. In a modification (Fig. 13, not shown) similar to that of Fig. 7, the plates (65, 66) are fluid-tight and the gas and liquid phases both pass through the downcomer tubes. As described the apparatus is a heat exchange for the liquifaction of natural gas.

Abstract: 1474052 Sliding clasp fasteners OPTI HOLDING AG 23 July 1974 [7 Aug 1973] 32495/74 Heading E2S A method of making a sliding clasp fastener having rows of thermoplastic coupling elements 1 secured to carrier tapes 5 by attachment means 8 with parts of the coupling elements of each row projecting outwardly beyond an adjacent edge 4 of the associated tape, and a slider to engage and disengage the two rows of coupling elements, comprises disposing additional thermoplastic material as a length of filament 10 upon said projecting parts of some of the coupling elements and longitudinally of the rows of coupling elements, and uniting the additional thermoplastics material to those projecting parts of the coupling elements to provide a stop member 2 for the slider, the additional thermoplastics material extending laterally of the rows of coupling elements in a direction towards the tape to a position short of the attachment means 8. As shown, a row of continuous coupling elements 1 is formed of synthetic thermoplastic profiled monofilament 3 which is attached, eg. by sewing 8, to a knitted textile stringer tape and which has parts 7 carrying coupling heads 6 which project beyond the inner edge 4 of the tape. A stop 2 is formed by placing an additional length of thermoplastic monofilament 10 and the parts 7 of a coupling element 1 between, e.g. an ultrasonic, welding device S and an anvil A, the width of the monofilament 10 being substantially equal to the width of the projecting parts 7. The device S can either fuse the interfaces of the projecting parts 7 and the length of monofilament or, cause a complete flow of thermoplastic material so as to form a homogeneous stop member. The monofilament 10 may be the same as that used for coupling elements 1. The rows of coupling elements may comprise individual elements, Fig. 3; and the monofilament 10 may have a lower softening point than that of the coupling elements 1. A bottom end stop member is formed while the two rows of coupling elements are interengaged.

Title: A system for determining the length of metal remaining to be rolled in a reversing hot metal mill
IPC: B21B37/00
Filed: 1962-08-24
Abstract: 1,010,276. Rolling. GENERAL ELECTRIC CO. Aug. 24, 1962 [Aug. 29, 1961], No. 32609/62. Heading B3M. A system for determining the length of metal remaining to be rolled in a reversing mill, so that the rolls can be slowed down to prevent the metal travelling too far from the rolls before reversing, comprises means for measuring the length of metal rolled in a first pass and for storing a representation thereof, reducing means for reducing this representation during a second pass, and compensating means for adjusting the representation in accordance with the increase in length resulting from the second pass. As hot metal 9 passes through rolls 11 and 13 a hot metal detector 15 causes a tachometer 24 to generate pulses which are counted by a first counter 17, until the detector 15 no longer detects the metal. At this stage a reverse control 16 receives a signal and causes motor control 14 to be reversed and the hot metal to be returned to the rolls, and the value in the first counter is transferred to a second counter 18. On reversing of the hot metal the detector again causes the tachometer 24 to transmit pulses corresponding to the length of the hot metal which are counted by the first counter and reduced in the second counter. A factor depending on the known reduction of the metal during the second pass is fed into a compensator 27 which adjusts the pulse rate through an adjuster 19 and therefore varies the value measured in the counter 18. A comparison of the value in counter 18 and of the speed of the motor 14 is made in a circuit 23 and an appropriate signal is sent from a screw-down control 26 to the motor 14 to slow down the rolls. A similar sequence is followed in subsequent passes.
